Hi all,
Sent info to jack. If anyone wants direct info I will send to requestors to

This may be a partially imperfect recollection in the details:
Laura Vertatschitsch worked on a DDR3 to CPU interface at SAO.  However, after 
substantial effort, she still saw irreducible bit errors at some low rate, 
detectable with write-readback testing for extended time periods.  I vaguely 
recall the difficulty in this design arises in crossing the clock domain 
boundary to the PPC perhaps causing metastability and requiring double 
buffering or similar.  In the end we gave up on this approach, and figured out 
how to dump our data via the FPGA and a 10 GigE port to a host computer with a 
suitable NIC.  This workaround is still successfully in use, though arguably 
the PPC 1 Gig Ethernet would have been a more convenient solution at the time.

Laura may be able to fill in the details.   Interested to see Mike worked on 
this, and assuming his interface is entirely error free, we’d love to see it on 
the repo.

More broadly speaking, has anyone ever used the DDR powerPC interface on 
ROACH2? Is it actually know to work with code as-provided in the mlib_devel / 
katcp repos?

Thanks,

Franco
